Definitions

  • the invention relates to a distributor for a pneumatically operating distribution machine for seeds, fertilizers and. like.
  • Distribution machines have been used for a long time of seeds, fertilizers and.
  • Known. in which the material to be conveyed by means of an air flow into one Distributor is promoted and through this distributor Distribution lines to the corresponding spreading devices arrives.
  • Often there is a need one or more distribution lines from the inflow shut off from fertilizer, seeds or the like to z. B. create a tramline or border areas when sowing not to fertilize or sow the field.
  • From DE-U-87 08 456 and EP-A-0 309 608 is for example a shut-off device known to the distribution line, and if this Shut-off device blocks the distribution line, it will Pending seed or fertilizer in the storage container dissipated via a derivative.
  • This barrier in the area of the distribution lines is disadvantageous even if the junction box for reasons of space within the storage tank located and especially when the level of the storage tank is located above the distributor.
  • DE-40 04 685 A1 is a distribution device known for example for seeds that have shut-off agents has so that certain discharge elements are closed can be, e.g. B. if a tramline should be created. These shut-off devices are in yours Opening position arranged so that it is part of the Form walls that form the flow channel for the material to be distributed form. However, since the barrier means between the actual distributor head and the discharge elements are arranged, there is a great risk that the shut-off device in the closed position with in front of it accumulates distributed material and with high technical effort is attempted to avoid such a risk of constipation to reduce.
  • shut-off devices are known from EP-0 328 858, which are arranged within the manifold to the to circumvent the disadvantages mentioned above. Execution the shut-off device inside the distributor head has proven itself and the shut-off devices can be swiveled arranged in front of the outlets of the distribution lines and when open they stand in the distribution room of the distributor. This will make the free distribution space constricted and this can lead to a uneven dosage of the goods to be distributed lead to the distribution lines.
  • the invention is based on the object of a distributor to provide for a distributor in which the shut-off devices for the distribution lines in the area of the distributor are arranged, but a precise Dosing of the goods to be distributed enables and is easy and inexpensive to manufacture.
  • the invention is based in particular on the idea off, a distributor of this type with shut-off means equip that these shut-off means in their rest position not the distribution of the goods to be distributed influence and only after moving to their closed position shutting off the respective distribution line (s) cause.
  • Distribution room 3 is arranged. From this distribution room 3 the distribution lines 4 go off or the connections for the distribution lines 4, and these distribution lines 4 ultimately lead to the application devices for the funded good.
  • a tramline Shutoff means 5 For a planned shutdown of the distribution lines 4 enable, for example if a tramline Shutoff means 5 are to be created in Range of exits from an open position to a Closed position spent so that the relevant distribution lines 4 are blocked off directly in the distribution room 3 and the blocked delivery devices are not conveyed deliver.
  • the shut-off means 5 are shown in FIG. 1 from sliders that are vertically movable and in their Opening position part of the immediate or even at a certain distance from the wall form a flow channel 7 to the distribution line 4.
  • the shut-off means 5 can, if necessary, be in a closed position brought by lowering it like it is shown on the left side of Fig. 1.
  • shut-off means 5 in its open position the free distribution of the conveyed material not affected at all within the distributor 1 and thus an exact dosage of the Goods to be conveyed to the individual distribution lines 4 allows.
  • the shut-off device 5 in The distribution space 3 of the distributor remains in its closed position 1 big enough to have a precise distribution on the to allow remaining distribution lines 4.
  • shut-off device 5 it is possible to use the shut-off device 5 to be arranged below the flow channel 7 or laterally as required.
  • shut-off means 5 are provided immediately before the exits to the distribution lines 4 are arranged.
  • Locking edges 12 of the Shut-off means 5 are triangular, with tips point to the feed pipe 2, on the one hand hard impact of the seed on the locking edges 12 and thus avoid injury to the seeds and secondly, to ensure an even distribution of the To achieve conveyed goods.
  • shut-off means 5 evenly over the circumference of the distributor 1 arranged to evenly dose the material to be conveyed to the unblocked distribution lines 4 to reach. If the number of distribution lines is 4 of a distributor 1 should be odd, so the Barrier edges 12 are designed asymmetrically.
  • Locking edges 12 or locking means 5 are also advantageous if an increased or decreased supply of the material to be conveyed to the neighboring one Distribution line is desired. Increased funding to the adjacent distribution line 4, for example then advantageous if the edge row effect should be exploited.
  • the shut-off means 5 designed as a flap in its open position is swung up and in a recess 8 place takes place so as a part of the wall of the flow channel to build; in its closed position it will Shut-off means 5 pivoted down, as shown in FIG. 3 can be seen. That is on the left side of Fig. 3 Shut-off means 5 in turn designed to be vertically movable, the shutoff means 5 is a curved baffle 9 to prevent damage to the To prevent seeds or the like.
  • the baffle 9 causes the material to be conveyed in the direction a discharge nozzle 10, the derived material returns to the area of the dosing device so that the derived conveyed material in turn to the distributor 1 can be transported. If the shut-off means 5 in its opening position is moved up automatically closed the discharge nozzle 10 and the Distribution line 4 opened.
  • shut-off means 5 is another embodiment a shut-off means 5 shown, this Shut-off means 5 is shown in a plan view. Due to the design of the baffle 9 shown Shut-off means 5 is achieved that the material to be conveyed on the concave central area of the baffle 9 meets the adjacent discharge nozzle, not shown 10 is directed while the material being conveyed on the outward-facing sides of the barrier 5 arrives on the neighboring distribution lines is directed. Through such a design of the baffle 9 of the shut-off means 5 is achieved that a certain percentage of the material to be conveyed to the surrounding area Delivery lines are directed so that this adjacent feed lines to an increased addition Receive funding.
  • the baffle 9 can easily the percentage of the derived in the discharge nozzle 10 Goods to be conveyed and the percentage of the neighboring Coulters of derived material to be changed. If e.g. B. the lateral discharge surfaces larger are trained, the percentage of that on the Neighboring shares increased and vice versa.
  • the shut-off means 5 can for example by means of Electric motors, electromagnets, hydraulic or Pneumatic cylinders individually or in certain groups be moved orderly.
